Figure 16.34. Example of creating a border from a selection

An image with a selection

After “Select Border”

The Select Border command creates a new
selection along the edge of an existing selection in the current image.
The edge of the current selection is used as a form and the new selection
is then created around it. You enter the width of the border, in pixels
or some other unit, in the dialog window. Half of the new border lies
inside of the selected area and half outside of it.

4.13.1. Activating the Command

You can access this command from the image menubar through
Select → Border.

Figure 16.35. The “Border” dialog window

Border selection by

Enter the width of the border selection in the box. The default
units are pixels, but you can also choose the units with the
drop-down menu.

Feather border

If this option is checked, the edges of the selection will be
feathered. This creates a smooth transition between the selection
and its surroundings. Note than you can't use the
Feather Edges option of the selection tools
for this purpose.

Lock selection to image edges

With this option enabled, an edge of an (usually rectangle)
selection remains unchanged if it is aligned with an edge of the
image; no new selection will be created around it.
